Hello I cannot edebug the following function (defun matlab-shell-render-html-anchor (str) "Render html anchors inserted into the MATLAB shell buffer. Argument STR is the text for the anchor." (if (string-match matlab-anchor-end str) (save-excursion (while (re-search-backward matlab-anchor-beg nil t) (let* ((anchor-beg-start (match-beginning 0)) (anchor-beg-finish (match-end 0)) (anchor-text (match-string 1)) (anchor-end-finish (search-forward matlab-anchor-end)) (anchor-end-start (match-beginning 0)) (o (matlab-make-overlay anchor-beg-finish anchor-end-start))) (matlab-overlay-put o 'mouse-face 'highlight) (matlab-overlay-put o 'face 'underline) (matlab-overlay-put o 'matlab-url anchor-text) (matlab-overlay-put o 'keymap matlab-shell-html-map) (delete-region anchor-end-start anchor-end-finish) (delete-region anchor-beg-start anchor-beg-finish) )))) ) When I do the cursor (with arrow jumps directly to the if line) Like (defun matlab-shell-render-html-anchor (str) "Render html anchors inserted into the MATLAB shell buffer. Argument STR is the text for the anchor." =>f (string-match matlab-anchor-end str) (save-excursion (while (re-search-backward matlab-anchor-beg nil t) (let* ((anchor-beg-start (match-beginning 0)) (anchor-beg-finish (match-end 0)) (anchor-text (match-string 1)) (anchor-end-finish (search-forward matlab-anchor-end)) (anchor-end-start (match-beginning 0)) (o (matlab-make-overlay anchor-beg-finish anchor-end-start))) (matlab-overlay-put o 'mouse-face 'highlight) (matlab-overlay-put o 'face 'underline) (matlab-overlay-put o 'matlab-url anchor-text) (matlab-overlay-put o 'keymap matlab-shell-html-map) (delete-region anchor-end-start anchor-end-finish) (delete-region anchor-beg-start anchor-beg-finish) )))) ) I don't understand this. For other functions in the matlab pkg edebug behaves as expected.
